Select a Map Source

or SD map card with additional chart information for a particular location (separate purchase required). See HELIX Control Head
for compatibility details.

(Map Source: Humminbird Basemap)
NOTE: Your control head may require a software update to display the Humminbird Basemap. See Update Software and visit our
Web site at humminbird.com for more information.
Install a microSD or SD Map/Chart Card
When you install a microSD or SD map or chart card, the control head automatically chooses the best map to display. You can also
change the map source manually. If your control head has two cards installed, you can choose which map source you want to use
(HELIX 8, 9, 10, 12 only).
1. Install a microSD or SD map/chart card into the control head card slot. See HELIX Control Head for compatibility details.
NOTE: Do not leave the card slot cover open. The slot cover should always be closed to prevent water damage to the unit.
Change the Map Source
When you install a microSD or SD map/chart card, the map source is changed automatically to match the microSD or SD map/
chart card map source. You can also change the map source manually.
When you change the map source, the available views and menus for the chart views also change, allowing you to add navigation
data, shading, alarms, and more.
1. Main Menu: Press the MENU key twice. Select the Chart tab.
2. Select Map Source.
3. Select the installed map/chart card location or a built-in map.
Auto: The best available map will be selected automatically.
Change Map Options
Change the Map Coordinate System (optional, Contour XD and Navionics map cards only)
Use Map Datum to change the map coordinate system used by the control head to match those of a paper map. Almost all
electronic charts use the WGS84 Map Datum and most likely do not require a setting change. (Default = WGS84)
1. Main Menu (Custom User Mode): Press the MENU key twice. Select the Chart tab.
2. Select Map Datum.
3. Press the RIGHT or LEFT Cursor keys to change the setting.
